PAPER-CLIP.

SPECIFICATION forming part of Letters Patent No. 501,86?, dated July 18,1893.

Application filed March 8, 1893.

To all whom it may concern:

Beit known that I, EDWARD T. BLAKE, a citizen of the United States ofAmerica, residing at Denver, in the county of Arapahoe and State ofColorado, have invented certain new and useful Improvements inPaper-Clips; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to the figures of referencemarked thereon, which form a part of this specification.

My invention relates to improvements in paper clips of that class usedin connection with a base generally composed of card board on which thepapers to be held by the clip are supported.

The novelty of this improvement relates more particularly to the mannerof applying the device to the card-board base whereby it not only holdsthe board securely in place, but is detachable at will.

My improved clip consists further of the features, hereinafter describedand claimed, and the same will be fully understood by reference to theaccompanying drawings, in

Y which is illustrated an embodiment thereof.

In the drawings, Figure 1 is a side elevation of the device attached tothe card board base. Fig. 2 is, a top or plan view of the same. Fig. 8is a front view, the movable clip being broken away.

Similar reference characters indicating cor-Y responding parts orelements of the mechanism in the several views, let the numeral 5designate the card board base upon which are supported a number ofsheets 6 held by the clip 7. g

The base 8 of the device consists of a clamp which when slipped over theend of the card board grips the Vsame automatically and tightly in therear of the sheet pad 6. This clamping base 8 is composed of sheetVmetal and consists of the bottom plate 8a which engages the undersurface of the board 5 and may be of any desired length. This bottomplate projects upwardly as shown at 8c and Serial Ilm/165,196.` (Nomodel.)

back to form the top part Sd which engages Athe upper surface of boardwhen the device is in place, the board being securely grasped betweenthe parts 8a and 8l of thebase.

Upon the part 8d are formed two vertical projections 9 formingsupportinglegs for the clip 5 provided with hinges 5 which are pivotedin the legs 9 by a spindle 10 which passes through coinciding aperturesformed in said legs and hangers. These parts 9 are preferably integralwith part 8d and formed by cutting strips of suitable dimensions andthen bending these strips upward to form the legs 9. The spindle 10carries a coil spring 12, the extremities 12 of which engage the top 8dYof the base while the central part is bent upward as shown at 10a toengage the under surface of the clip in the rear of the spindle wherebythe clip is made to grasp the sheet pad 6. The free extremity or edge ofpart 8d is bent upward slightly as shown at 8d2 to facilitate theinsertion of the board 5. It will be observed that as the rear extremityof the clip is pressed and the pad 6 released, the top 8d is made tograsp the board more tightly since there is a downward pressure thereonthrough the medium of the `spring 12, the extremities of which engagethe part S as heretofore explained.

Having thus described my invention, what I claim is 1. In a paper clip,the combination of the supporting base consisting ofA the bottom plateand the top part formed into a clamp to receive the board, and thespring-actuated clip pivotally mounted on the clamp, substantially asdescribed.

2. The combination of the clamping base composed of the top and bottomplates, and the spring actuated clip pivoted on legs carried by the toppart ofY the clamp substantially as described.

3. The combination of the clamping base composed of the top and bottomplates, the clip pivoted on the spindle carried by legs formed on thetop plate of the clamp and av spring attached to the spindle andengaging the clip and the top of the clamp, substantially as described.

4:. The combination of the clamping base composed of the lcop and bottomplates formed from an integral piece of sheet metal, the clip pivoted onlegs carried by the base, and a 5 spring so located as to aetuate theclip and simultaneously press upon the top plate of the clamping base,substantially as described.

In testimony whereof I affix my signature in presence of two Witnesses.

EDWARD T. BLAKE.
